Answer:

Step-by-step explanation:
Given

Translation = 3 units down
Vertical stretch of 2 to give g(x)
Required

3 units down translation
A function is translated down as follows:

Where k is the number of units.
So:


Vertical stretch of 2
A function is vertically stretched as follows;

Where a is the units stretched.
In this case:

So:



-7 it’s closer to -7 than -6.5
Start the number line from 0 and put divisions at 1/12. Then mark at 4/12 for plant A and indicate this was its growth in the first week. Then, make another mark up to 6/12 and indicate this was the plant's growth in the second week.
For plant B, make one mark at 7/12 and indicate that this is plant B's growth in the first week.
After two weeks, plant A has a height of 6/12 inches and plant B has a height of 7/12 inches, so B is taller.
